RHSA-2006:0658 - Security Advisory

Topic

New Wireshark packages that fix various security vulnerabilities are now
available. Wireshark was previously known as Ethereal.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

Wireshark is a program for monitoring network traffic.

Bugs were found in Wireshark's SCSI and SSCOP protocol dissectors. Ethereal
could crash or stop responding if it read a malformed packet off the
network. (CVE-2006-4330, CVE-2006-4333)

An off-by-one bug was found in the IPsec ESP decryption preference parser.
Ethereal could crash or stop responding if it read a malformed packet off
the network. (CVE-2006-4331)

Users of Wireshark or Ethereal should upgrade to these updated packages
containing Wireshark version 0.99.3, which is not vulnerable to these
issues. These packages also fix a bug in the PAM configuration of the
Wireshark packages which prevented non-root users starting a capture.
